SPECIFICATION forming part of Letters Patent No. 603,680, dated May 10,1898.

Application filed November 23, 1896. Serial No. 613,057. (No model.)

T at whom it may concern.-

Be it known thatwe, JAMES G. W. ENTWIS- TLE, FRED STARR, ORREN P.TALLEY, and HENRY E. LORANOE, citizens of the United States, residing atChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Vapor Generators and Burners; andwe do declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use-the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The invention relates to that class of vapor generators and burnerswhich are adapted for use in connection with coal or wood stoves; and itconsists of a chambered plate adapted to fit within one of thestove-holes, and being served by an induction-tube for the delivery ofliquid, such as kerosene, and being provided with a combustion-chamber,to which the vapor generated from the liquid is delivered by a suitablenipple, an aperture for the escape of the flame into the fire-box of thestove and thence to its flue being provided in the wall of thecombustion-chamber.

The object of the invention is to secure complete vaporization of theliquid before its delivery to the combustion-chamber.

It has for other objects the convenient attachment of the service-tube,leading from the oil-reservoir to the induction tube, and the cleaningof the combustion-chamber, these objects being accomplished by means ofthe construction hereinafter set forth.

In the drawings, Figure 1 is a plan View of a portion of an ordinarycoal or wood stove having our generator and burner applied thereto. Fig.2 is a sectional View on the line 2 2 of Fig. 1. Fig. 3 is an edgeelevation of the generator and burner. Fig. 4 is a sectional View on theline 4 4 of Fig. 1. Fig. 5

is a bottom plan section on the line 5 5 of Fig. 2, and Fig. 6 is asectional View on the line 6 (i of Fig. 4. Figs. 7 and 8 are details ofthe clamping device by means of which the burner and its appurtenancesmay be attached to the stove.

The top of an ordinary cookingstove is shown at A, and one of its coversis designated at a and its smoke-flue at a.

The generator and burner comprises a plate B, adapted to fit within oneof the stove-holes, and having radialribs b,upon which any cookingutensils, such as a kettle, may stand, and is centrally apertured andprovided with an internal annular chamber 0. A bowl-shaped shell D isfixed to the under side of the plate 13, thereby forming acombustion-chamber d, the wall of the shell D being at one sideapertured, as indicated at d, for the escape of the flame. Liquid is ledto the chamber 0 by means of an induction-pipe E, and the vaporsdeveloped within the chamber 0 are discharged by means of a nipple F,leading through the bottom of the plate B into the chamber (1 at a pointremote from the induction-pipe E, as shown diametrically oppositethereto, and directly over the aperture 01.

- The nipple F has a right-angled bend, so that its tip f, which isflattened, is directed to the center of the chamber d, and is locatedimmediately below the central aperture of the plate B. i

The generator and burner is provided with liquid from a reservoir H,(indicated only by dotted lines in Fig. 1,) supported upon a verticaltube g, which leads to a horizontal tube G, connected with theservice-pipe E, the latter being provided with a needle-valve ofordinary construction, which we have not deemed it necessary to show indetail, which is controlled by means of avalve-stem e. Thejointconnecting the pipes G and g is swivele'd, so that the latter pipe maybe thrown to ahorizontal position for convenience in filling thereservoir, and this joint consists of a centrally-perforated disk K,secured to the lower end of the pipe g and fitting within a cap M, whichis secured by means of an apertured neck 0 to the pipe G. The disk K andcap M are secured together by means of screws 70, passing throughsegmental apertures m m in the cap and entering the disk, so that thedisk is free to rotate within the cap to the extent of the length of thesegmental slots. A spring T, secured to the periphery of the cap M, isprovided with a lug t, adapted to enter suitable apertures in the rim ofthe cap M and in the edge of the disk K, these two KOO apertures beingso located that they register when the pipe 9 is vertical, and the jointis consequently securely locked in that position. A gasket P isinterposed between the disk K and the cap M, surrounding a neck g, whichprojects from the face of the disk through the cap and is apertured toform a continuation of the aperture Q in the disk. The aperture Q is ofmuch less diameter than the pipe G for better protection against leakageof this swiveled joint, the capacity of the pipe Gbeing ample to rapidlyconvey the liquid away from the joint, thereby reducing the backpressure,whichwould tend to give rise to leakage. The pipe G restswithin an adjustable chair U, which is secured by means of any suitableclamping device, as V, to the top A of the stove.

A rotatable sleeve R fits within the central aperture of the plate B. Toits lower end is fixed a finger S, which extends laterally almost to theedge of the shell D and is in contact with the under surface of theplate B, so that by rotating the sleeve R by means of any suitable toolthe finger S is caused to sweep theunder surface of the plate B, inorder to remove any accumulation of soot.

In use a little liquid is discharged into the combustion-chamber d andignited, thereby developing sufficient heat to vaporize the liquiddischarged into the chamber 0 by turning the valve-stem e. The flamebeing directed away from the aperture (1 heats the generator to a hightemperature, thereby insuring the complete vaporization of the liquid.The flame escapes from the combustion-chamber through the aperture d,and circulatin g through the fire-box and flues of the stove, heats thelatter in an efficient manner.

We claim as our invention- 1. In a vapor generator and burner, thecombination with a centrally-apertured plate having an annular chambersubstantially coextensive with its body, of a laterally-apertured shellsecured to the lower side of the plate to form therewith acombustion-chamber, an induction-tube entering the chamber of the plate,and a burner-nipple leading from such plate-chamber, remote from theinduction-pipe, to the combustion-chamber and being directed away fromthe aperture of the shell.

2. In a vapor generator and burner, the combination with acentrally-apertured plate having an annular chamber substantiallycoextensive with its body, of a laterally-apertured shell secured to thelower side of the plate to form therewith a combustion-chamher, aninduction-tube entering the chamber of the plate, and aburner-nippleleading from such plate-chamber, remote from the induction-pipe, to thecombustion-chamber, a 1:0- tatable sleeve fitted within the centralaperture of the plate, and a finger attached to the sleeve and adaptedto frictionally sweep the lower surface of the plate.

3. The combination with a vapor generator and burner, of a service-pipehaving a swiveled joint, comprising a centrally-apertured cap havingsegmental slots and being attached to'one section of the pipe, and acentrallyapertured disk fitted rotatably within the cap and fixed to thecooperating section of the pipe, a pair of headed pins passing throughthe segmental slots and fixed within the disk, and a nipple leading fromthe aperture of the disk through the cap and being of less ca pacitythan the pipe-section to which the cap is attached.

In testimony whereof we affix our signatures in presence of twowitnesses.
